Title: Multiplier
Inventor: MARUYAMA RYOJI
IPC: G06G7/161
Filed: 1988-06-20
Abstract: PURPOSE:To reduce an error included in an output and to obtain a highly accurate multiplier by providing the multiplier with a correcting function for correcting an error generated in a conversion means due to the alternate inputs of an input signal obtained through a switching means and its inverted signal. CONSTITUTION:A switch 22 is turned on and off by the output of a timing circuit 25 and a switch 23 is turned on and off by the output of the circuit 25 inverted by an inverter gate 24. The circuit 25 continuously oscillates pulses at the duty ratio of 1 to 1 in a frequency band sufficiently slower than the oscillation frequency of pulse width converters 3, 4 and an oscillator 5 to switch the switches 22, 23 at the time ratio of 1 to 1 under input voltages Va, the inverse of Va. Consequently, an error included in a pulse width changing signal generated in a conversion means can be remarkably offset between the input signal and its inverted signal and sharply reduced. Thereby, highly accurate multiplication reducing the influence of an error due to the conversion means can be attained.

Title: Switching indicating valve
Inventor: MATOBA YOSHINORI
IPC: F16K37/00
Filed: 1978-12-04
Abstract: PURPOSE: To improve reliability of a valve opening indicator readily and unexpensively by means that a turning motion of a handle is converted into a parallel motion coaxial with a stem by use of a slide rod whose motion at its conical end is changed into a swing motion of a valve opening indication needle by the effort of a lever.  
     CONSTITUTION: As a valve handle is turned for opening a valve, a stem 3 and a disc 4 united with it come turning out. Simultaneously a disc 2 coupled with the groove of the disc 4 is accompanied with its out motion, which is united with a slide rod 1. The lower end B of a lever 6 is contact with a cone part A of the slide rod 1 so that said lower end B turns clockwise around a fulcrum 7, while the upper end C turns counterclockwise by a load of a spring 8. As a result an opening indication needle 9 fixed on a turning element 11 whose high spot 12 is joined with a notch formed in the upper end C of the lever 6 swings noticeably. The swing can be seen easily to confirm the grade of valve openings.
